In a cleaning method of a drink filling system provided with a drink supply pipe line for supplying a drink to a filling machine ( 2 ) and an aseptic chamber ( 3 ) surrounding at least the filling machine, the cleaning method is performed by executing program including at least two of first, second and third programs, wherein the first program corresponds to an aseptic carbonated drink and executes a COP treatment performed for an interior of the aseptic chamber and a CIP treatment performed for an interior of the drink supply pipe line, the second program corresponds to a high acidic drink and executes the COP treatment and an SOP treatment performed for the interior of the aseptic chamber and a CIP treatment and an SIP treatment performed in the interior of the drink supply pipe line, and the third program corresponds to a low acidic drink and executes the COP treatment and the SOP treatment performed for the interior of the aseptic chamber and the CIP treatment and the SIP treatment performed in the interior of the drink supply pipe line, and wherein either one of the three programs is enabled to be selectively executed, and in a case where the drink is an aseptic carbonated drink, the first program is selected, in a case where the drink is a high acidic drink, the second program is selected, and in a case where the drink is a low acidic drink, the third program is selected, to thereby clean the interiors of the aseptic chamber and the drink supply pipe line before filling of the drink in accordance with the selected program.

TECHNICAL FIELD

The present invention relates to a method for cleaning a system forfilling a container such as PET bottle with drink.

BACKGROUND TECHNOLOGY

In a conventional technology in an aseptic drink filling system, when itis required to change a kind of drink to fill a container such as bottleso as to change tea, for example, now in the container to another drinksuch as coffee with milk, a CIP (Cleaning In Place) treatment is firstperformed to an inside of a drink supply pipe line or arrangement in anaseptic filling system and an SIP (Sterilizing In Place) treatment isthereafter performed (see, for example, Patent Document 1).

The CIP treatment is performed, for example, by flowing a cleaningliquid prepared with water to which alkaline chemical agent such ascaustic soda is added in a flow path from an inside of a pipe line of adrink filling path to a filling nozzle of a filling machine, andthereafter, by filling a cleaning liquid prepared with water to whichacidic chemical agent is added. According to such treatment, remainingcontent of previously filled drink adhering to the drink filling pathcan be removed (see, for example, Patent Documents 1, 2, and 3).

The SIP treatment is performed, for example, by circulating steam orheated water through the drink filling path cleaned by the CIP treatmentmentioned above. According to such treatment, the interior of the drinkfilling path can be sterilized to thereby provide an aseptic condition(see, for example, Patent Document 1).

Further, in an aseptic filling system, a filler for automaticallyfilling a container with drink, and such filler is surrounded by anaseptic chamber to be shut off from an exterior. Further, since dropletsor like of the drink previously filled in a drink filling operationsticks on an inside of the aseptic chamber, a COP (Cleaning Out OfPlace) treatment is performed to the aseptic chamber at a time when thekind of drink for filling is changed to thereby remove the droplets orlike of the drink stuck in the previous filling operation to the innerwall of the aseptic chamber and an outer surface of an equipment such asfiller disposed inside the aseptic chamber.

The COP treatment is performed, for example, by atomizing water into theaseptic chamber in a state of shower.

Furthermore, there is a fear such that bacteria or like may invade intothe aseptic chamber during various operations or workings at a time ofchanging a kind of drink for filling, and hence, an SOP (Sterilizing OutOf Place) treatment is also performed) see, for example, Patent Document4).

The SOP treatment is performed in a manner such that hydrogen peroxidewater, for example, in a state of mist or shower, is supplied into theaseptic chamber, and thereafter, hot air is blasted into the asepticchamber to thereby dry remaining hydrogen peroxide.

EMBODIMENT FOR CARRYING OUT THE INVENTION

Hereunder, an embodiment of the present invention will be explained withreference to the accompanying drawings.

A structure of a drink filling system is first explained herein, andthen, a method for cleaning this drink filling system will be explained.

As shown in FIG. 1, a drink filling system includes a drink preparationapparatus 1 and a filling machine 2 for filling a container such asbottle with drink. The preparation apparatus 1 and the filling machine 2are connected through a drink supply pipe line. The filling machine 2 issurrounded by an aseptic chamber 3.

The preparation apparatus 1 is an apparatus for preparing, for example,tea drink, fruit drink and the like at a predetermined composition rate(blended rate), and since such preparation apparatus is known one,detailed explanation thereof is omitted herein.

The filling machine 2 is a machine provided with a wheel (not shown)that rotates a number of filling nozzles 2 a at high speed in ahorizontal plane, and this machine for filling bottles 4 travelling insynchronism with a peripheral speed of the wheel under the fillingnozzles 2 a with a constant amount of drink from the filling nozzles 2a, respectively, while rotating in conformation with the rotation of thewheel. Further, this filling machine 2 is also known one, andaccordingly, detailed explanation thereof is omitted herein.

The drink supply pipe line of this drink filling machine is providedwith three, i.e., first, second and third, supply pipe lines 5, 6, 7 soas to selectively fill a container with either one of non-sterilizedcarbonated drink, high acidic carbonated drink, low acidic carbonateddrink, high acidic drink and low acidic drink.

The first supply pipe line 5 is for supplying the non-sterilizedcarbonated drink to the filling machine 2, and as shown in FIG. 2 withthick line, a carbonic acid adding apparatus 8, a first aseptic tank 9,a switch (change-over) valve 10, and a second aseptic tank 11 in thisorder from an upstream side toward a downstream side on the pipe linefrom the preparation apparatus 1 toward the filling machine 2.

The carbonic acid adding apparatus 8 is an apparatus for injectingcarbonic acid into a predetermined drink flowing inside the pipe line,and the aseptic tanks 9 and 11 are buffer tank or storage tank fortemporarily storing the drink to which the carbonic acid is injected.These carbonic acid adding apparatus 8 and the aseptic tanks 9, 11 areknown ones, and hence, detailed explanations thereof are omitted herein.

The non-sterilized drink mentioned herein is a drink having CO₂ pressureof more than 1.0 kgf/cm² (20° C.) and including no plant and/or animalcomponent or composition, and in such drink, since metabolism ofbacteria is not carried out, the drink is not subjected to becomecorrupt by the bacteria even if the drink fills a container such asbottle 4 without sterilizing inside the drink supply pipe line, thefilling machine 2 and the aseptic chamber 3.

As shown in FIG. 2, the non-sterilized carbonated drink is produced bypreparing a drink by the preparation apparatus 1 and sending such drinkto the carbonic acid adding apparatus 8, in which carbonic acid is mixedwith such drink. This non-sterilized carbonated drink is delivered tothe filling machine 2 via the first aseptic tank 9, the switch valve 10,and the second aseptic tank 11, and a constant amount of such drinkfills, from the nozzle 2 a of the filling machine 2, each of the bottles4 which are now travelling below a nozzle 2 a.

A CIP treatment apparatus is provided for the first supply pipe line 5and the filling machine 2.

That is, as shown with thick line in FIG. 5, the CIP treatment pipe line12 is connected to the first supply pipe line 5, and these pipe linesand associated members are combined, which constitutes a circulationpath as an entire structure for flowing cleaning water or like.

More specifically, this circulation path extends from the carbonic acidadding apparatus 8 as starting end of the first supply pipe line 5toward the filling machine 2, and then extends from the filling nozzle 2a of the filling machine 2 and is connected to the starting end of theCIP treatment pipe line 12, the terminal end of which is connected tothe carbonic acid adding apparatus 8, thus constituting a closed loop.The connection between the filling nozzle 2 a of the filling machine 2and the CIP treatment pipe line 12 is performed, though not shown, byapplying a cup provided for the CIP treatment pipe line 12 to the frontend portion of the filling nozzle 2 a of the filling machine 2 by anactuator.

An introduction conduit 12 a for cleaning water or like is connected tothe circulation path through a valve manifold 13, and a cleaning watersupply source 14, and a cleaning chemical liquid supply source 15 areconnected to the upstream side of the introduction conduit 12 a throughswitch valves 16, respectively.

Various other types of valves, pumps or like are provided for thecirculation path and the introduction conduit, which are however notshown in the attached drawings.

Further, a COP treatment apparatus is also provided for the first supplypipe line 5 and the filling machine 2 in addition to the CIP treatmentapparatus.

That is, as shown with a thick line in FIG. 5, a cleaning water supplysource 17 is connected to the aseptic chamber 3 through a COP treatmentpipe line 17 a, and a spray nozzle or sprinkler head, both not shown,for spraying or atomizing the cleaning water into the aseptic chamber isprovided to a portion of the aseptic chamber 3 at which the COPtreatment pipe line 17 a faces the interior of the aseptic chamber 3.Furthermore, a switch valve 17 b and a pump, not shown, are provided forthe COP treatment pipe line 17 a.

The second supply pipe line 6 is one for supplying a high acidiccarbonate drink or low acidic carbonated drink to the filling machine 2,and as shown with a thick line in FIG. 3, a pipe line from thepreparation apparatus 1 to the carbonate acid adding apparatus 8 in thepipe line from the preparation apparatus 1 to the filling machine 2constitutes a bypass circuit line, and a pipe line from the carbonateacid adding apparatus 8 to the filling machine 2 is commonly used forthe first supply pipe line. In the bypass pipe line, a sterilizingmachine 18 and a third aseptic tank 19 are provided from the upstreamside to the downstream side as viewed in the drink flow.

Herein, the high acidic carbonated drink is a high acidic drink mixedwith carbonic acid. The high acidic carbonated drink is a drink having apH of less than 4.6 (pH<4.6) prescribed according to indication of theU.S. FDA, but in consideration of the growing characteristics of gem bypH, it may be preferred that a drink having pH of less than 4 (pH<4.0)is defined as high acidic drink.

With the high acidic drink, as long as mold, yeast and nursing cell ofbacteria are sterilized, even if spore fungus remains alive, it isdifficult for the spore fungus to grow, and, hence, the high acidicdrink is a drink which does not become corrupt because of prevention ofgermination of the fungus.

On the other hand, the low acidic carbonated drink is a low acidic drinkto which carbonic acid is mixed. If the low acidic drink is defined bythe indication of the FDA, it is a drink having pH of not less than 4.6(pH≧4.6). However, in consideration of the growing characteristics ofthe fungus by pH, it may be preferred that a drink having pH not lessthan 4.0 (pH≧4.0) is defined as a low acidic drink, which issufficiently sterilized.

The low acidic drink is a drink that has a fear of being corrupted evenif the spore fungus as well as mold and yeast are not sterilized.

As shown with thick line in FIG. 3, the high acidic drink or low acidicdrink is produced by being prepared by the preparation apparatus 1,delivering the prepared one to the carbonic acid adding device 8 via thesterilizing machine 18 and the third aseptic tank 19, and being mixedwith carbonic acid in the carbonic acid adding device 8. The thusprepared high acidic carbonated drink or low acidic carbonated drink isthen delivered to the filling machine 2 via the first aseptic tank 9,the switching valve 10 and the second aseptic tank 11. Thereafter, suchdrink fills each bottle 4 travelling below the filling nozzle 2 a of thefilling machine 2 with a predetermined amount.

The CIP and SIP apparatus are provided for the second supply pipe line 6and the filling machine 2.

That is, as shown with thick line in FIG. 7 or 9, the pipe lines 20, 20a of the CIP and SIP apparatus are connected to the second supply pipeline 6 to thereby constitute two circulation paths.

More specifically, a valve manifold 18 a is provided for a pipe lineconnecting the sterilizing machine 18 and the third aseptic tank 19, anda bypass route 18 b bypassing the sterilizing machine 18 is provided onthe upstream side of the valve manifold 18 a. These bypass route 18 band the sterilizing machine 18 constitute a first circulation path. TheCIP and SIP treatment pipe line 20 extending from the valve manifold 13is connected to this first circulation path.

Further, the CIP and SIP treatment pipe line 20 a extending from thevalve manifold 13 is connected to the downstream side from the valvemanifold 18 a in the pipe line connecting the sterilizing machine 18 andthe third aseptic tank 19. The CIP treatment pipe line 12 extends fromthe filling machine 2 toward the valve manifold 13. Thus, the secondcirculation path is constituted by the third aseptic tank 19, thecarbonic acid adding device 8, the first aseptic tank 9, the secondaseptic tank 11 and the filling machine 2.

Furthermore, the hot water supply source 15 and the aseptic water supplysource 25 for the SIP treatment are connected to the introductionconduit 12 a connected to the valve manifold 13 in addition to thecleaning water supply source 14 and the cleaning chemical liquid supplysource 15.

The third supply pile line is for supplying the high acidic drink or lowacidic drink to the filling machine 2, and as shown with a thick line inFIG. 4, among the pipe lines from the preparation apparatus 1 toward thefilling machine 2, a part from the preparation apparatus 1 to theswitching valve 10 is formed as a bypass line partially commonly usedwith the second supply pipe line 6, and a part from the switching valve10 to the filling machine 2 is commonly used with the first and secondsupply pipe lines 5 and 6. On the way of such bypass route, thesterilizing machine 18 and the third aseptic tank 19 are provided fromthe upstream side toward the downstream side as viewed in the drink flowdirection.

Herein, the high acidic drink or low acidic drink is a drink not mixedwith carbonic acid.
